Extremely light and portable 13.1" , f5 Dobsonian by Discovery, only 2 months old. This scope was in limited production and is no longer availabe. (I'm moving up to larger, GPS sytem). This is one helluva great inexpensive scope! Comes with Telrad, 26mm and 6.5mm Super Plossl 1.25" oculars, 2 threaded color planetary filters, accessory tray, and my homemade handy-dandy movable cart for freewheeling portability with locking casters. So simple even I can use this fun scope!! It gathers so much light I can easily get M33 even with a mall polluting my northern view. Can't beat this for the price. Despite it's 65" length, it's so light one person can easily move and set this up.
